The Science of Coal Dust Suppression

- Control: this relates to how the water to the system is controlled. For example, it may be controlled by the presence of coal on the conveyor or by the motion of the belt, so that water can be isolated before entering the system. - Filter: this ensures the water is sufficiently clean or free of contaminants, so that the system operates correctly.

Longwall mining - Wikipedia

Longwall mining is a form of underground coal mining where a long wall of coal is mined in a single slice (typically 0.6–1.0 m (2 ft 0 in–3 ft 3 in) thick). The longwall panel (the block of coal that is being mined) is typically 3–4 km (1.9–2.5 mi) long and 250–400 m (820–1,310 ft) wide.
